I'm less concerned about animation unless its an action, Mecha, fighting, etc... kind of show. Like for instance, two other animes I would say that animation took a back seat to the story would be Maid-Sama and Kimi no Todoke. IMO, those two and Kotoura-san i'd put head to head with a lot of other animes. I'd much rather have an awesome story with not excellent animation than terrible story and awesome animation. Just my thoughts.

school girls being attack while kotoura all better yet still bit scared get manabe to stay at her place til manabe get chance with fear level on manabe over 9000 cue demon-mori to box'd manabe.

police arrive at school give asking students if any info going give kotoura read criminal's mind but can't say give got other students "HMM" on kotoura so esp idea go like scooby-doo to catch the crook.

well at kotoura's grandpa call in invite them to dinner give all formal to a small food place to really a hotel til yikes it that "mom".

give "mom" still bitter while kotoura try to show to try patch but "mom" not notice til enter manabe perv power it still show bit something within the "mom"

So her mum does feel something for her then? It wasn't the best catch up moment form them two after all these years.
Some funny moments in this episode as always with the series. Kotoua grandfather funny as always.
And we know who was behind the attacks after the ED.
